LUCIUS GOSS, OF UPPER MONTCLAIR, NEIV JERSEY.

STEREOTYPE- -PLLATE.

SPECIFICATION forming part of Letters Patent No. 395,435, dated January 1, 1889.

Application filed March 19, 1888. Serial No. 267,653- (No model.)

To aZZ whom it may concern:

Be it known that I, LUCIUs (1oss,ol:' lIpper Montclair, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Stereotype-Ilates, of which the following is a full, clear, and exact description.

My invention consists of a stereotype-plate cast with several spaced or separated eol umns joined at the ends, whereby the longitudinal sawing of the columns is avoided, and whereby the edges of all of the columns in the plate may be trimmed in the planing-machine at one operation.

Reference is to behad to the acconmanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a stereo type-plate cast in accordance with my invention. Fig. 2 is a plan view of the castingbox which I prefer to use for casting my new stereotype -plate, the said box being Fig. 3 is a sectional elevation of the same, taken on the line r of Fig. 2. Fig. iis a transverse sectional elevation takencn the line y y of Fig. 3. Il1ig. 5 is a detailed sectional elevation of the stereotypeplate.

The stereotype-plate A is composed of several columns, a u, of reading-matter, cast integral with the end pieces, 13 B, and spaced or separated by the slots (10. The casting by which this form of plateis made is formed or provided with partitions or cores D D between the columns, so that in the pouring of the metal the cores will form the spaces or slots (1. The casting-box as a whole comprises the main box E, the outer lid, F, and the inner lid, (t. The box E receives the matrix H, and the said lids F G are hinged to said outer box, E. The said partitions D are by preference formed wholly upon the inner face of the outer lid, F. Slots .I are formed in the inner lid, G, to correspond in position and size to the 1:)artitions D, so that when the lids are closed the said. partitions will close through the slots J and rest closely against the matrix H, as shown clearly in Fig. 4.

The partitions D and slots J are of less length than inner lid, G, so as to form spaces K K, in which the metal, flows to form the end pieces, B B, to unite the columns. The inner surface of the main box E is by preference formed with ribs (1, over which the matrix is placed and against which the partitions D close; but these ribs may be omitted, in which case the matrix will be made perfectly plain. The inner surface of the illner lid is ribbed, as shown atff, to reduce the weight of the casting, and between each pair of ribs f is formed the lip 1 which latter forms the groove 71 at the back of each column. In each of the grooves h is formed a diagonal slot wholly within the groove 7L that is to say, one edge of the slotj forms an angle, 2 with one edge of the groove 72, while the other edge of the slot forms an angle, 1', with the opposite side of the groove. In this manner the raw edge formed by sawing the diagonal slot will in no manner interfere with the fitting of the columns in the press, and the labor of trimming off said raw edges is avoided.

By casting the plate with spaced columns the labor of sawing the columns apart is obviated, and by uniting the spaced columns by the end pieces, B I in casting the whole plate, with its numerous columns, may be planed and trimmed at one o 'ieration, and the columns are easily separated by sawing them from the end pieces, B I3.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The stereotype-plate A, formed with columns a, slots (J between said columns, and the end pieces, B 13, by which the columns are united, substantially described.

2. The plate A, formed with the grooves 71, and diagonal slots j, forming the angles 2' i with the sides of the groove 71., substantially as described.

LUCIUS GOSS.
